Introduction. Sealing abilities of two self-etch adhesives were evaluated after two aging processes: storage in water and thermocycling. Materials and Methods. Cl V cavities were prepared on the buccal and lingual aspects of 48 human premolars, with cervical margins 1 mm below the CEJ. Clearfil Protect Bond (CPB) and BeautiBond (BB) (two-step and one-step self-etch adhesives, resp.) were applied, each to half of the cavities and restored with composite resin. Each group was randomly subdivided into 4 subgroups (n=12) and evaluated for dye penetration after 24 hours, after 3000 thermocycling rounds, after a 6-month water storage, and after 3000 thermocycling rounds plus 6-month water storage, respectively. Data was analyzed using SPSS 11.5 and Kruskal-Wallis and Mann-Whitney U tests (α=0.05). Results. There were no significant differences in enamel and dentin microleakage between the adhesives (P=0.683; P=0.154). Furthermore, no significant differences were observed in enamel microleakage of each one of CPB and BB (P=0.061 and P=0.318, resp.). However, significant decrease was observed in subgroups 3 and 4 (P=0.001) for CPB dentinal margins. Conclusion. In this study, limited aging procedures had no influence on marginal integrity of composite resin restorations bonded with self-etch adhesives of CPB and BB. Furthermore, CPB dentinal sealing improved after aging.

Objectives: This in-vitro study aimed to evaluate the effect of cavity disinfection with chlorhexidine (CHX) on marginal gaps of Class V composite resin restorations bonded with a universal adhesive using self-etch and etch-and-rinse bonding strategy. Materials and Methods: Sixty sound human premolars were randomly assigned to two groups (n=30): group 1 (CHX) and group 2 (no CHX). Each group was divided into two subgroups (n=15) according to the bonding strategy of the universal adhesive (self-etch or etch-and-rinse). Class V cavities were prepared on the buccal surfaces of the teeth. The occlusal and gingival margins of the cavities were placed in enamel and dentin, respectively. In the first and second subgroups of both groups, the All-Bond Universal adhesive was applied with self-etch and etch-and-rinse bonding strategy, respectively. After restoration and thermocycling, the samples were sectioned, and marginal gaps at the gingival margins were measured in micrometer (µm) under a stereomicroscope. Two-way analysis of variance (ANOVA) was used to compare marginal gaps between the groups and the subgroups. Results: The mean marginal gap size was significantly affected by cavity disinfection (P=0.001) and bonding strategy (P=0.002). However, the interaction effect of these two factors on the mean marginal gap size was not significant (P=0.79). Conclusion: The use of CHX resulted in larger marginal gaps at the gingival margins of Class V composite resin restorations. Irrespective of disinfection, the self-etch bonding strategy resulted in larger marginal gaps compared to the etch-and-rinse bonding strategy.

SUMMARY The aim of this randomized controlled clinical trial was to compare the clinical effectiveness of different polishing systems and self-etch adhesives in class V composite resin restorations. A total of 164 noncarious cervical lesions (NCCLs) from 35 patients were randomly allocated to one of four experimental groups, each of which used a combination of polishing systems and adhesives. The two polishing systems used were Sof-Lex XT (Sof), a multistep abrasive disc, and Enhance/Pogo (EP), a simplified abrasive-impregnated rubber instrument. The adhesive systems were Clearfil SE bond (CS), a two-step self-etch adhesive, and Xeno V (XE), a one-step self-etch adhesive. All NCCLs were restored with light-cured microhybrid resin composites (Z250). Restorations were evaluated at baseline and at 6, 12, 18, and 24 months by two blinded independent examiners using modified FDI criteria. The Fisher exact test and generalized estimating equation analysis considering repeated measurements were performed to compare the outcomes between the polishing systems and adhesives. Three restorations were dislodged: two in CS/Sof and one in CS/EP. None of the restorations required any repair or retreatment except those showing retention loss. Sof was superior to EP with regard to surface luster, staining, and marginal adaptation (p<0.05). CS and XE did not show differences in any criteria (p>0.05). Sof is clinically superior to EP for polishing performance in class V composite resin restoration. XE demonstrates clinically equivalent bonding performance to CS.

ABSTRACT Objective To evaluate the effect of 0.2% chlorhexidine digluconate (CHX) as a pretreatment of two types of adhesive systems on color stability of composite resin restorations. Methods Forty bovine teeth were prepared (6x6x2mm) and randomly divided into 4 groups (n=10): SB - total etch adhesive (Single Bond 2, 3M ESPE); SB + CHX - dentin pretreatment with CHX (30 seconds) followed by SB application; Adh - self-etch adhesive (AdheSE, Ivoclar Vivadent); Adh + CHX - pretreatment with CHX (30 seconds) + followed by Adh application. The teeth were restored with Filtek Z350XT (3M ESPE) and photoactivated for 40 seconds. Color measurements (EasyShade, VITA) were performed following the CIE Lab scale at baseline, 1 and 3 months (distilled water/37°C). The mean color change values (?E) and coordinates (L*, a* and b*) were statistically analyzed (2-way ANOVA, repeated measures, Bonferroni, p <.05). Results Results showed that there was a reddening and yellowing of the restorative material after 3 months, differing (p <.05) from 1 month. There was no difference (p >.05) regarding the treatment with CHX. Conclusions The 0.2% CHX adhesive pretreatment did not produce greater color changes in composite resin restorations irrespective of the type of adhesive system used. However, time had significant effect on the change, regardless of the substrate treatment.
